Metal Profile: Iron Properties and Characteristics
Nowadays, the iron ore normally goes through a process of sintering before entering the stack. The sintering process forms pieces of ore that are 10-25mm, and these pieces are then mixed with coke and limestone. The sintered ore, coke, and limestone are then poured into the stack where it burns at 1,800 degrees Celsius. Coke burns as a source of heat and, along with oxygen that is shot into ...Get Price
What Are the Different Uses of Iron Ore? (with .
Banded iron ore has more iron deposits than do some ore samples. Steel production consumes the vast majority of iron ore produced around the world. To make steel, firms start by crushing and pre-processing ore before smelting it to free the trapped metal with a heat and chemical reaction. This can be used to make so-called "pig iron," solid ...Get Price
